Detailed explanation-1: -The main reason is that they contain chloroplasts and produce food through photosynthesis. However, they lack many other structures of true plants. For example, algae do n ot have roots, stems, or leaves. Some algae also differ from plants in being motile.
Detailed explanation-2: -Unlike plants, algae don�t have roots to draw nutrients from the soil. Instead, nutrients are taken directly from the water. Most importantly, like plants, algae use photosynthesis to create and store energy.
Detailed explanation-3: -Algae are more simple than aquatic plants as they lack a true root, leaf, and stem system. Some algae species drift or swim, while others are attached to stones or aquatic plants in the water. All algae contain chlorophyll (a green pigment).
